Y To @ZZ wh-m it may concern.'

Be it known' that I, CHARLES PAFF, ai citizen of the-United States, and a resident of New York, in the county of New York and State of New York, have inventedcertain new and useful mproveinents in a Metallic Tie, of which the following is a full, clear, and exact specification.

This invention relatesto a class of devicesy adapted to be used in the construction of railway beds. n v

My invention has for its object primarily to provide a tie designed to be employed for supportingthe rails on a railway bed, and

which contemplates certain improvements in the form of tie disclosed in my Patent No. 1,830,276 issued February 10, 1920, whereby the tie in entirety may be inade of sheet metal of a given thickness in a manner so that its parts having the greatest weakness will be reinforced, in order that such parts will effectually withstand the loads imposed on the tie without tending to prematurely weaken. l The invention resides mainly in the provision kof corrugations or spa-ced ribs on an elongated body of approximately the shape of an inverted U in cross section, and the corrugations are disposed transversely to extend from the base'of each vertical wall to and including the opposite lengthwise marginal edge parts of the longitudinal wall of the body. When the tie is in use the rails are laid upon the longitudinalwall, and the strain of the weight of the load will then be imposed upon the junctures or elbows of'the walls of the tie. To sustain the longitudinal wall when und-er pressure the junctures of the vertical walls with the longitudinal wall are reinforced by making the curvilinear dimensions of the corrugations of the junctures larger than the curvilinear dimensions of the other parts of the corrugations.

A further object of the invention is to provide a metallic tie of a simple, efficient and durable construction which may be made in any appropriate size.

"With these and other objects in view, the invention will be hereinafter more fully described with reference to the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views,y

andwill then be pointed out in the claims at the end of the description.

In the drawing, Figure 1 is a fragmentary view showing plan of'a number of my improved metallic ties when laid to support railway rails. Y

Fig. 2 is a side elevation of Vone of the` ties with the rails mounted thereon, the latter being shown in section.

Fig. 3 is an enlarged detail sectional view f taken on the line 3-3 of Fig. 2, and

Fig. 4 is a fragmentaryview showing an enlarged section taken on the line 4 4 of Fig. 3. I The tie is preferably made of sheetmetal in any standard or preferred size as well as being formed to provide an elongated body 10 of substantially the shape of an inverted U in cross section. Spaced parallel vertically disposed side members or walls or legs 1 1, 12 and a longitudinally disposed bridging member or wall or plate -13 are thereby provided. The juncturesor elbows,

as 141 and 15, of the vertical side walls with the bridging wall are 4preferably rounded, instead of being formed with sharp angular OFFICE.

junctures, in order to avoid weakening the body when made of sheet metal, since angularjunctures would tend to prematurely g1 ve way in this form of tie as the rails are laid upon the bridging wall crosswise, and the junctures must, therefore, withstand the main strain ofthe weight of the load. The part of the bridging wall 13 between the round or curved junctures 14 and 15 is made`V olf greater thickness, as at 16, than the vertical walls. Both of the side walls 11 and 12 are of corresponding widths, and on the lower lengthwise edges' of theV side walls may be outwardly extending feet or anges, as 17 and 18.

While these parts of the present improved tie are similar in formations to like parts of the body portions of each member of the tie disclosed in my Patent No. 1,330,276, the tie as improved is designed to be used singly, instead of being constructed of two con nected substantially U-shaped body parts. A great saving in the consumption of inaterial is thereby accomplished. To prevent tendency of the verticalside walls 11 and 12 from spreading the foot flanges 17 and 18 are tied by a suitable number of binding rods or bars, as 19, arranged at intervals across the mouth of the hollow interior of the tie. All of the binding rods may be alike in formations, and each rod has bent or hook ends, as 20 and 21, of shapes which Y corrugations.

coliform with the shapes of the foot flanges 17 and 18 of the body 10 as well as snugly fitting the flanges. In the ends of the bridging wall 13 of the body 10 may be provided openings 22 and 23 similar to those shown in the Aabove named patent for allowing the interior of the body to be filled with ballast.

In order to make the tie as light in weight as possible and to provide it with suflicient strength, corrugations or ribs as 24 and 25, are formed transversely in the vertical side wall 11, 12 and in the bridging wall 13 to extend from the foot flanges 17 and 19 upwardly across the curved junctures 14 and 15 to vand including the marginal edge parts lengthwise of the bridging wall 13. In the form of tie of the patent above referred to corrugations are also employed, but when rails, as 26 and 27, are laid on the tie crosswise of its end parts, as illustrated, the pressure of the weight of loads uponthe rails will be largely directed upon the curved junctures 14C and 15 of the walls of the body of the tie. To reinforce these junctures the curvilinear dimensions of the parts 28 and 29 of the corrngations at these Y junctures are made larger than the curvilinear dimensions of the other parts of the rIhat is, the parts 28 and 29 of the corrugations are enlarged so that their outer free edges are of somewhat rightangular formations, while the junctures 14 and 15 of the body 10 are curved in a circle of longer radius. By reinforcing the tie in this manner its strength to withstand the weight imposed thereon will be approximately uniform throughout.

Inv the foregoing description, Ihave embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore, I reserve to myself theright to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent Y 1. In a metallic tie formed of sheet metal to provide an elongated body ofsubstantially the shape of an inverted U'in cross section, transverse corrugations extending from the base of each vertical wall of the body to and including the adjacent lengthwise marginal edge parts of the bridging Wall of the body and the curvilinear dimensions of the corrugations being deeper at the junctures of the walls of the body than the other parts of the corrugations.

2, The combination, in a metallic tie formed of sheet metal, of an elongated body of substantially the shape of an inverted U in cross section, and spaced ribs extending from the base of each vertical wall of the body to and including the adjacent lengthwise marginal edge parts of the longitudinal wall ofthe body and the said ribs being larger at the junctures of the walls ofthe body than at other parts of the ribs.

3. The combination, in a metallic tie formed of sheet metal, of spaced bent ribs formed on an elongated body of substantially the shape of an inverted U so that the elbows of the ribs protrude from the round corners of the vertical walls with the longitudinal wall of the body to strengthen theV junctures of the walls of the body by forming the elbows of the ribs of less radius than the radii of the junctures of the Walls, foot flanges on the free edges of the vertical walls, and spaced crosswise binding rods having their ends held to the foot flanges.

This specification 'signed and witnessed this 18th day of December, VA. D. 1920.
